Like with global, static is a keyword linking a variable specially. unset() will
completely destroy the variable with all links it might have. This is expected
behaviour, or at least a known side-effect. With the current way of handling variables
internally, this is not going to change.
This isn't stressen enough in the manual, so changing to documentation problem.

Doing unset() on a static variable causes it to forget the fact that it is static for
the rest of the function.
e.g.
<?
function abc() {
static $a = 123;
echo "On entry, a = $a\n";
unset($a);
$a = 456;
}
abc();
abc();
?>
should give 123 then 456. It gives 123 and 123.
Replacing unset($a) with $a = null, or removing the unset() entirely has the desired
result of giving 123 then 456.
